Nanthwan is definitely a super host. She is super responsive. she made sure we were not facing any problem during our stay, she answered all the questions I had about travelling local.
The place overall is good, in the heart of the city. walkable distance from ICONSIAM, multiple ferry points, massage centres, bars, restaurants, three Indian restaurants in walking distance. Asiatique is near as well.
Talking about small cons:
You would have to carry your luggage one floor, then there is a luggage lift.
The apartment is not super windy if you are looking for that, but the aircons eliminate the need of that.
Overall I would not hesitate to come back. I stayed with my elderly parents and we had a good time.
